1.Watson and Crick knew that the triple helix model of DNA that Linus Pauling had proposed was incorrect. What evidence did they

have for such a conclusion?. . . 2.The work of Rosalind Franklin provided a key piece of data for Watson and Crick’s model of DNA.  Summarize that evidence and how it was pivotal to the correct model being built.

Use the information from Parts B and C to solve this problem. If a rabbit of genotype AaBb is bred to a rabbit of genotype AaBb,
Kipish [7]

The question is incomplete and the complete question is

Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (aabb) with 6-cm ears is mated to a true-breeding male (AABB) with 16-cm ears.

Answer:

AABb or AaBB

Explanation:

We know that,

aabb genotype - 6 cm

AABB genotype- 16-cm

To calculate the length of earlobe contributed by each allele in a genotype is :

1. length of aabb/4 or 6/4= 1.5 cm (a and b contribute for 1.5 cm each)

2. Length of AABB/4 or 16/4= 4 cm (A and B contribute for 4 cm each)

Now to have the earlobe to be 13.5 cm long then the genotype must be

13.5 = 4+4+4+1.5 or A+A+B+b or A+a+B+B

Therefore, the genotype will be-either AABb or AaBB

Which diagrams shows reaction pathway that absorbs energy?
postnew [5]

Question:

<em>The diagram shows the potential energy changes for a reaction pathway.</em>

Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.

Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.

Answer:

Part 1: The diagram illustrates an endothermic  reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.

Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.

Which do you think would adapt and survive overtime to a mass extinction? A starfish or an eel?
Harlamova29_29 [7]

Answer:

Starfish

Explanation:

This is an opinion questions, so there really isn't a right or wrong answer.  You could just as easily choose Eel.  Your task is to pick one and defend your reasoning.

I chose starfish because starfish have a long history of demonstrated adaptability to a wide variety of conditions.  Their armored skin protects them from a variety of predators, as does the poison that many of them contain.  They have the ability to regrow limbs, and even regrow entire starfish from certain body parts.  When it comes time to breed, starfish meet together in groups.  Each female releases a few million eggs from the gonads in each of her arms.  Each male then releases billions of sperm from each gonad in each of his arms, thus covering the eggs with sperm to fertilize them.
